Solution

1. Preparation

Tools Required:
- Oil dipstick
- Flashlight or work light
- UV dye kit (if needed)
- UV light (if using dye)
Ensure the vehicle is on a level surface and the engine is cool before starting the inspection.

2. Inspect the Engine Bay

Sub-steps:
1. Open the hood and secure it.
2. Use a flashlight to examine the oil filter and oil pan for wetness or residue.
3. Look for any oil seeping from the valve cover gasket.
4. Check hoses and seals that may be contributing to leaks.

3. Check the Oil Drain Plug and Filter

Sub-steps:
1. Using a wrench, carefully inspect the oil drain plug for tightness; if loose, tighten it to the manufacturer's specified torque.
2. Inspect the oil filter for any tightness and signs of oil seepage. If it appears loose, tighten it.
3. If the filter is damaged or leaking, replace it with a new one.

4. Conduct a UV Dye Test (if necessary)

Sub-steps:
1. Pour the UV dye into the engine oil filler cap.
2. Run the engine for about 10-15 minutes to circulate the dye.
3. Turn off the engine and use a UV light to inspect areas of the engine for glowing leaks.
